I have updated Debian across 4 major releases without issues. I have daily updates on Fedora without issues. I had to do maintenance probably monthly on Manjaro.
Arch doesn’t do things for you, therefore Manjaro doesn’t do things for you. This means you are the one who needs to do the maintenance and upgrade config files and such. It is interesting, it is formative, but it is not for beginners who might get the impression that Linux needs constant maintenance and breaks often.
